can't unroot/relock GNex - please help - Samsung Galaxy Nexus

I walked through the following steps to put the stock OS back on my device...
adb reboot bootloader
fastboot flash bootloader bootloader-toro-primekk15.img
fastboot reboot-bootloader
fastboot flash radio radio-toro-i515.ek02.img
fastboot reboot-bootloader
fastboot flash radio-cdma radio-cdma-toro-i515.ek05.img (Note: This one takes a couple minutes. Be patient)
fastboot reboot-bootloader
fastboot -w update image-mysid-icl53f.zip
I now have the stock OS loaded and can boot alright, unlocked. When I get back into the OS I turn debugging on and then head back to adb. I can browse to my device through the USB but get the following error when attaching to my device.
c:\android\android-sdk\platform-tools\adb shell
[email protected]:/ $ adb reboot bootloader
adb reboot bootloader
error: device not found
1|[email protected]:/ $
Further, if I run "fastboot devices" from my command prompt I get no devices returned.
What am I missing?? I need to get this device relocked to send back in for warranty quickly. I'm trying to get the device locked back up. Any help you can provide is appreciated!
Edit: Resolved now

nevermind... whew... figured it out.

Mark threads as solved and update first post with whats happening, so one doesnt waste time like i did.
No need to double post for that.

[Q] fastboot stuck

i have just flashed a new recovery, and everything is just fine until i typed this:
fastboot reboot
and it does not reboot fastboot,stucks on first screen but!
pull out battery and entering by hardware key works, all fastboot, bootloader, my ROM, the new recovery.
so that confuses me, i can enter manually, but by adb i cant?
ADB works at the Bootloader and Recovery.
Fastboot works at the Fastboot mode.
Fastboot != ADB
Different commands, different purpose.
If you need reboot to fastboot command is:
"fastboot reboot-bootloader"
"fastboot reboot" just reboots your phone.

[HOW TO]Step by Step Flash TWRP 2.0 on Linux

this is what I had to do on Linux Mint 12 but should work with most ubuntu based distros
1: download twrp
2: if you dont already have it then you need to download the linux fastboot binary, extract the .zip and place the extracted file in your androidsdk/platform-tools directory
2: place the file you downloaded from TWRP into your androidsdk/platform-tools directory
3: connect your fire to your computer and disable mass storage mode
4: open a terminal and cd to your androidsdk/platform-tools directory and enter the following commands pressing enter after each line
Code:
./adb shell
su
idme bootmode 4002
then back out of the adb shell by
Code:
exit
exit
then
Code:
./adb reboot
after it reboots to the "Kindle Fire" boot screen its time to flash the recovery
Code:
fastboot -i 0x1949 boot twrp-blaze-2.0.0RC0.img
once flashed and it installs and boots to the "firefirefire" screen (screen with the yellow sign and text that says "press power for recovery" you have to change the boot mode back out of fastboot
Code:
sudo ./fastboot oem idme bootmode 4000
sudo ./fastboot reboot
it should reboot to the "firefirefire" screen, to enter recovery press and hold the power button until it turns from green to orange then let go. You should boot into TWRP and be able to make your first backup.
from now on if you dont want to go into recovery then just let it sit and it will boot normally
Thanks to all the Teamwin members, agrabren for the port, pyrostic for testing, pokey9000 for the "FireFireFire" bootloader, and I am sure there are more but I dont know who you are so thank you.
if you can donate to these guys please do becuase without them we would just have an e-reader.
I am not responsable for any damage that YOU may cause buy following these directions.
not sure where i went wrong. i followed every step, it flashed, im stuck at the yellow triangle guessing im in fastboot.
i do fastboot oem bootmode 4000 and it gets stuck at waiting for devices.
issue the command with sudo
Nevermind, wasn't using ./ when I was issuing commands. As usual, need to pay better attention.
Thanks OP. Sweet.
My Fire got stuck at the splash screen after issuing the command idme bootmode 4002 and it won't load up. I can't get adb to recognize it anymore. Any advice?

adb wont recogonize it after you change the boot mode thats where you issue the fastboot commands

Download this file and place it in the folder your fastboot is located in: http://techerrata.com/file/twrp2/twrp-blaze-2.0.0RC0.img
do the following
open a command window where fastboot is located:
Step 1:
Code:
fastboot -i 0x1949 boot twrp-blaze-2.0.0RC0.img
if your window says "waiting for device" then reboot your device. if it boots into TWRP 2.0 then you are set move to Step 3. if it still says "waiting for device" close the window and then then open a command window where fastboot is located and do step 2.
Step 2:
Code:
fastboot -i 0x18d1 boot twrp-blaze-2.0.0RC0.img
if your window says "waiting for device" then reboot your device. if it boots into TWRP 2.0 then you are set move to Step 3. If it is still not doing anything, this is where my knowledge is no good anymore, and you should consult someone else.
TWRP should be showing on your screen. Close your old fastboot window and open a new command window where ADB is located. Proceed to Step 3.
Step 3:
Code:
adb shell
idme bootmode 4000
reboot
your device should reboot, and if you had problems with Step 3 try the following from your ADB command window
Code:
su
adb kill-server
adb start-server
adb devices
your device should be listed. If so try Step 3 again.
hope this helps or at least puts you in the right direction.

Sounds like you are in fastboot, but I would expect to see the yellow triangle logo and not the Kindle Fire one. Anyway, try to see if running the following works:
Code:
./fastboot oem idme bootmode 4000
./fastboot reboot

Tried setting bootmode with fastboot, but it just sits there at "< waiting for device> ". Tried rebooting Kindle but fastboot is still hanging up there.
EDIT: Ok, had to pass "-i 0x1949" to fastboot. Got the device back, going to try it all over again

I'm on Fedora 16 x86_64. I did all of the adb interactions on a Windows 7 system, however it looks like adb isn't set up correctly on this Fedora box I'm on now. I have (what I think at least) the udev rules set for Kindle Fire. Looks like I have some more reading to do!
EDIT: adb up and running. For anyone who has this issue, add "0x1949" to ~/.android/adb_usb.ini, and restart adb!

Alright, my week-old Kindle Fire does not agree with this procedure. The twrp image does not seem to be flashing at all (fastboot returns after .009s and device never reboots to recovery)
try rebooting manually n see if u get fastbot.

woot for fedora! anyway, i set things up via /etc/udev/rules.d/51-android.rules and at first I had this...
SUBSYSTEM=="usb", SYSFS{idVendor}=="1949", MODE="0666"
and everything was cool. but after flashing twrp, i noticed there was firefirefire 1.0 out where previously i had flashed .9 so i thought id update I went to update and after putting the device in fastboot mode, it rebooted to the bootloader where fastboot wasnt recognizing the device started digging around and found windows users having driver issues and thought to myself... we dont have drivers BUT we do have rules!! added this line to the udev rules
SUBSYSTEM=="usb", SYSFS{idVendor}=="18d1", MODE="0666"
and everything working as it should again

Mac OS X Fastboot Mode <Waiting for Device>

Hi, I am trying to Re-Lock my Galaxy Nexus GSM version, I've downloaded the SDK files (adb-mac and fastboot-mac) and all the image files and I am trying to execute the following commands:
adb reboot bootloader
fastboot flash bootloader bootloader-toro-primekk15.img
fastboot reboot-bootloader
fastboot flash radio radio-toro-i515.ek02.img
fastboot reboot-bootloader
fastboot flash radio-cdma radio-cdma-toro-i515.ek05.img
fastboot reboot-bootloader
fastboot -w update image-mysid-icl53f.zip
fastboot reboot-bootloader
fastboot oem lock
With the phone in normal mode I connect the USB cable to the computer, start Terminal windows and run the first command, "./adb-mac reboot bootloader" and the phone will boot into the "Fastboot Mode", then I try to execute "./fastboot-mac devices" to make sure the phone is connected and properly detected and I get nothing.
If I try to execute "./fastboot-mac flash bootloader bootloader-toro-primekk15.img" I get the message <waiting for device> and it will stay there forever.
Do you know what might be the problem ?, is there other method to do this ?, go back to Stock ROM and Re-Lock the device ?, thanks
You must also install the Samsung usb drivers. I have no idea how to do this in mac. A simple search will help you tho.

Flashing to stock Android NPD90G from TWRP error: "remote: unsupported command"

Flashing to stock Android NPD90G from TWRP error: "remote: unsupported command"
Fixed flashing error "remote: unsupported command" when flashing a Pixel C back to stock
I used TWRP and SuperSU to root and modify the buildprops to enable and get an early look at the windowing in Android N beta on my Pixel C release 5 ahead of time.
When Release 5 NPD90G was available I decided to flash back to stock from Developer Preview 4 NPD56N rooted with SuperSU and flashed with TWRP. I like root - I run Ubuntu and Win 7. I don't mind running a rooted device if it doesn't have all my work and financial data. When the final N release is out, the Pixel C will become my work machine. It's almost there.
I'm naturally paranoid. I change my long passwords frequently and use 2 factor authentication for everything. So if I can, I'll take a stock release. See my instructions for wiping Android devices: How to wipe an Android Phone: the paranoid editon
I could not flash the NPD90G stock bootloader because of an error "remote: unsupported command"
Here's how I fixed it.
Updated the SDK manager including SDK Tools and USB drivers.
With the Pixel C in recovery mode, {hold the power key and volume down}
In TWRP mount System and reboot to recovery
>ADB Shell.
From ADB Shell I ran
>fwtool vbnv write dev_boot_fastboot_full_cap 1 to reenable Fast boot.
Then I changed from TWRP to Fastboot mode {power button plus hold the volume up button}
>fastboot erase userdata
>fastboot erase boot
>fastboot erase cache
>fastboot erase recovery
>fastboot erase system
See Note 1. Below
>fastboot flash bootloader bootloader-dragon-google_smaug.7900.27.0.img
>fastboot reboot-bootloader
>fastboot flash bootloader bootloader-dragon-google_smaug.7900.27.0.img
>fastboot reboot-bootloader
Note 1.
The first time through I flashed the following line items which resulted in the resting robot Andi. I don't think I needed to do this, but if the above instructions don't work, run the following before continuing for {flash bootloader bootloader-dragon-google_smaug.7900.27.0.img}
>flash bootloader bootloader-dragon-google_smaug.7900.27.0.img
>fastboot reboot-bootloader
>fastboot reboot-bootloader
>fastboot flash system system.img
>fastboot flash boot boot.img
>fastboot flash recovery recovery.img

It's nice of you to help a fellow XDA user. But I suspect he's already solved his problem of three months ago.....
Hi guys
I have the same problem:
- the bootloader is unlocked (Coreboot menu says so)
- fastboot says "secure: yes" but "unlocked: yes" too
- "fastboot flashing get_unlock_ability" returns "1"
- "fastboot flashing unlock" says that the bootloader is already unlocked
But I have no recovery and if I try to fastboot boot recovery.img it fails with signature verification error
Can I do something to unbrick the device?
Regards

My solution is very simple:
fastboot flashing lock
fastboot flashing unlock
fastboot reboot
And now let it boot.... and wait.
After the (failed) reboot check again: Now you can write all partitions... worked with my Pixel C
Make sure you have the latest version of fastboot and adb. I get these errors almost every month if I don't update.
https://developer.android.com/studio/releases/platform-tools.html
@stevep2007, thank you so much! I've been dealing with this "remote: unsupported command" nonsense for days now after trying to revert back to an older Oreo version of Lineage. This did the trick!
How can I solve the problem when my Pixel C is not unlocked? My Pixel made an update and after installing the Update I got the green little man. Now I have no Chance to activate USB debugging etc. Its also not possible to install twrp.img
How can I go to ADB shell with locked bootloader? Or isn't it possible?
Fastboot devices shows me my tablet. ADB devices also show my tablet with "sideload".
But every try to flash my Pixel fails. I alway get the message .... remote: unknown command.......fastboot error: command failed
flash-all.bat showes that all "*.img are missing" error: command failed... unknown command etc.......
So any idea to get my Pixel working again? ADB shell would make it I think. But how with locked bootloader.

fastboot unresponsive

I haven't touched my LG G7 in a while, so I decided to flash original boot_a/b to be able to OTA update. But when I boot into bootloader, fastboot can't do anything, command simply hangs until I interrupt it.
It is not just that the:
Code:
fastboot flash boot_a boot_v10p.img
fails, but not even:
Code:
fastboot flashing get_unlock_ability
works.
Fastboot recognize the device properly:
Code:
# fastboot devices
LMG710EMabd8a3d8 fastboot
Any thoughts?
